Preventing Unauthorized Access to Secured Information Systems Using Tokenized Authentication Techniques

ABSTRACT

A computing platform may receive, from a client portal server, a request to authenticate a user to a user account associated with a client portal provided by the client portal server. Based on receiving the request to authenticate, the computing platform may send, to a social messaging server, an authentication token request message. Subsequently, the computing platform may receive, from the social messaging server, an authentication token. Thereafter, the computing platform may validate the authentication token received from the social messaging server. Based on validating the authentication token received from the social messaging server, the computing platform may generate a validation message directing the client portal server to provide the user with access to the user account. Subsequently, the computing platform may send, to the client portal server, the validation message directing the client portal server to provide the user with access to the user account.

BACKGROUND

Aspects of the disclosure relate to providing information security and preventing unauthorized access to resources of an information system. In particular, one or more aspects of the disclosure relate to preventing unauthorized access to secured information systems using tokenized authentication techniques.

As organizations increasingly provide electronic portals via which various users may access, view, and/or modify information, including client information, ensuring the safety and security of information maintained by such organizations and/or made available via such portals is increasingly important. In many instances, however, it may be difficult to ensure the safety and security of such information while also optimizing the efficient and effective technical operations of the computer systems that maintain such information and/or provide such portals.

SUMMARY

Aspects of the disclosure provide effective, efficient, scalable, and convenient technical solutions that address and overcome the technical problems associated with providing information security and preventing unauthorized access to resources of an information system by implementing tokenized authentication techniques.

In accordance with one or more embodiments, a computing platform having at least one processor, a memory, and a communication interface may receive, via the communication interface, and from a client portal server, a request to authenticate a first user to a first user account associated with a client portal provided by the client portal server. Based on receiving the request to authenticate the first user to the first user account associated with the client portal provided by the client portal server, the computing platform may send, via the communication interface, and to a social messaging server, a first authentication token request message. Subsequently, the computing platform may receive, via the communication interface, and from the social messaging server, a first authentication token. Thereafter, the computing platform may validate the first authentication token received from the social messaging server. Based on validating the first authentication token received from the social messaging server, the computing platform may generate a first validation message directing the client portal server to provide the first user with access to the first user account. Subsequently, the computing platform may send, via the communication interface, and to the client portal server, the first validation message directing the client portal server to provide the first user with access to the first user account.

In some embodiments, the request to authenticate the first user to the first user account associated with the client portal provided by the client portal server may include information indicating that a first tokenized link included in a notification generated by the client portal server and sent via a social messaging service provided by the social messaging server has been selected. In some instances, the first tokenized link may include a unique identifier linked to the first user account associated with the client portal provided by the client portal server and a first interface of the client portal provided by the client portal server.

In some embodiments, the first authentication token request message may include information identifying a first social messaging service account associated with the social messaging service provided by the social messaging server.

In some embodiments, the first authentication token received from the social messaging server may include information indicating that the first user is authenticated to the first social messaging service account associated with the social messaging service provided by the social messaging server.

In some embodiments, the first validation message directing the client portal server to provide the first user with access to the first user account may include information indicating that the first user has been authenticated to the first user account based on the first authentication token received from the social messaging server.

In some embodiments, prior to generating the first validation message directing the client portal server to provide the first user with access to the first user account, the computing platform may generate a first step-up authentication prompt for a first registered client computing device linked to the first user account. Subsequently, the computing platform may send, via the communication interface, and to the first registered client computing device linked to the first user account, the first step-up authentication prompt generated for the first registered client computing device linked to the first user account. Thereafter, the computing platform may validate a first response to the first step-up authentication prompt generated for the first registered client computing device linked to the first user account. In addition, the first validation message directing the client portal server to provide the first user with access to the first user account may be generated based on validating the first response to the first step-up authentication prompt generated for the first registered client computing device linked to the first user account.

In some embodiments, the computing platform may receive, via the communication interface, and from the client portal server, a request to authenticate a second user to a second user account associated with the client portal provided by the client portal server. Based on receiving the request to authenticate the second user to the second user account associated with the client portal provided by the client portal server, the computing platform may send, via the communication interface, and to the social messaging server, a second authentication token request message. Subsequently, the computing platform may receive, via the communication interface, and from the social messaging server, a second authentication token. Thereafter, the computing platform may validate the second authentication token received from the social messaging server. Based on validating the second authentication token received from the social messaging server, generate a second validation message directing the client portal server to provide the second user with access to the second user account. Subsequently, the computing platform may send, via the communication interface, and to the client portal server, the second validation message directing the client portal server to provide the second user with access to the second user account.

In some embodiments, the request to authenticate the second user to the second user account associated with the client portal provided by the client portal server may include information indicating that a second tokenized link included in a notification generated by the client portal server and sent via a social messaging service provided by the social messaging server has been selected. In some instances, the second tokenized link may include a unique identifier linked to the second user account associated with the client portal provided by the client portal server and a second interface of the client portal provided by the client portal server.

In some embodiments, the second authentication token request message may include information identifying a second social messaging service account associated with the social messaging service provided by the social messaging server.

In some embodiments, the second authentication token received from the social messaging server may include information indicating that the second user is authenticated to the second social messaging service account associated with the social messaging service provided by the social messaging server.

In some embodiments, the second validation message directing the client portal server to provide the second user with access to the second user account may include information indicating that the second user has been authenticated to the second user account based on the second authentication token received from the social messaging server.

In some embodiments, prior to generating the second validation message directing the client portal server to provide the second user with access to the second user account, the computing platform may generate a second step-up authentication prompt for a second registered client computing device linked to the second user account. Subsequently, the computing platform may send, via the communication interface, and to the second registered client computing device linked to the second user account, the second step-up authentication prompt generated for the second registered client computing device linked to the second user account. Thereafter, the computing platform may validate a second response to the second step-up authentication prompt generated for the second registered client computing device linked to the second user account. In addition, the second validation message directing the client portal server to provide the second user with access to the second user account may be generated based on validating the second response to the second step-up authentication prompt generated for the second registered client computing device linked to the second user account.

These features, along with many others, are discussed in greater detail below.

DETAILED DESCRIPTION

In the following description of various illustrative embodiments, reference is made to the accompanying drawings, which form a part hereof, and in which is shown, by way of illustration, various embodiments in which aspects of the disclosure may be practiced. It is to be understood that other embodiments may be utilized, and structural and functional modifications may be made, without departing from the scope of the present disclosure.

It is noted that various connections between elements are discussed in the following description. It is noted that these connections are general and, unless specified otherwise, may be direct or indirect, wired or wireless, and that the specification is not intended to be limiting in this respect.

Some aspects of the disclosure relate to passing messenger session context to a mobile banking application. For example, a bank server may send a customer a notification via a social networking messenger service. The notification may include a link and/or other embedded content that, when selected, cause the customer's mobile device to open a mobile banking application to a specific access point. In the transition to the mobile banking application, contextual information may be passed from the messenger application to the mobile banking application. For instance, if the customer received a notification about a low balance alert via the messenger service and selected a link to transfer funds, the mobile banking application may open to a transfer funds screen (e.g., after prompting the customer to provide fingerprint input for biometric authentication).

FIGS. 1A and 1B depict an illustrative computing environment for preventing unauthorized access to secured information systems using tokenized authentication techniques in accordance with one or more example embodiments. Referring to FIG. 1A, computing environment 100 may include one or more computing devices.

Client portal server 120 may be configured to provide one or more portal interfaces to one or more client devices. For example, client portal server 120 may be configured to provide a customer portal, such as an online banking portal, to one or more customers of an organization, such as a financial institution, who may use one or more client computing devices to access the portal, such as client computing device 160, client computing device 170, and client computing device 180, as illustrated in greater detail below. In some instances, in addition to being configured to provide an online banking portal associated with a financial institution to one or more customers of the financial institution and/or their associated computing devices, client portal server 120 also may be configured to provide a mobile banking portal associated with the financial institution to various customers of the financial institution and/or their associated mobile computing devices. Such portals may, for instance, provide customers of the financial institution with access to financial account information (e.g., account balance information, account statements, recent transaction history information, or the like) and/or may provide customers of the financial institution with menus, controls, and/or other options to schedule and/or execute various transactions (e.g., online bill pay transactions, person-to-person funds transfer transactions, or the like).

Client support server 130 may be configured to initiate and/or provide one or more client support sessions. For example, client support server 130 may include and/or integrate with one or more client support servers and/or devices, such as one or more customer service representative devices used by one or more customer service representatives of an organization (which may, e.g., be a financial institution operating client portal server 120), to connect one or more customers of the organization with one or more customer service representatives of the organization via one or more chat sessions and/or other client support sessions.

Administrative computing device 140 may be configured to provide one or more interfaces that allow for configuration and management of one or more other computing devices and/or computer systems included in computing environment 100. Social messaging server 150 may be configured to provide a social messaging service, as illustrated in greater detail below. For example, social messaging server 150 may be operated by and/or otherwise associated with a social networking service (which may, e.g., be different from and/or not associated with a financial institution and/or other organization operating client portal server 120). Social messaging server 150 may, for instance, provide one or more social messaging user interfaces to various users and/or user devices, such as client computing device 160, client computing device 170, and/or client computing device 180, as illustrated in greater detail below.

Client computing device 160 may be configured to be used by a first customer of an organization, such as a financial institution. In some instances, client computing device 160 may, for example, be registered with the organization and/or one or more computer systems in computing environment 100, such that the organization and/or the one or more computer systems maintain one or more records linking client computing device 160 to the first customer of the organization, as illustrated in greater detail below. Client computing device 170 may be configured to be used by a second customer of the organization (who may, e.g., be different from the first customer of the organization). In some instances, client computing device 170 may, for example, be registered with the organization and/or one or more computer systems in computing environment 100, such that the organization and/or the one or more computer systems maintain one or more records linking client computing device 170 to the second customer of the organization, as illustrated in greater detail below. Client computing device 180 may be configured to be used by a third customer of the organization (who may, e.g., be different from the first customer of the organization and the second customer of the organization). In some instances, client computing device 180 may, for example, be registered with the organization and/or one or more computer systems in computing environment 100, such that the organization and/or the one or more computer systems maintain one or more records linking client computing device 180 to the third customer of the organization, as illustrated in greater detail below.

In one or more arrangements, client portal server 120, client support server 130, administrative computing device 140, social messaging server 150, client computing device 160, client computing device 170, and client computing device 180 may be any type of computing device capable of receiving a user interface, receiving input via the user interface, and communicating the received input to one or more other computing devices. For example, client portal server 120, client support server 130, administrative computing device 140, social messaging server 150, client computing device 160, client computing device 170, and client computing device 180 may, in some instances, be and/or include server computers, desktop computers, laptop computers, tablet computers, smart phones, or the like that may include one or more processors, memories, communication interfaces, storage devices, and/or other components. As noted above, and as illustrated in greater detail below, any and/or all of client portal server 120, client support server 130, administrative computing device 140, social messaging server 150, client computing device 160, client computing device 170, and client computing device 180 may, in some instances, be special-purpose computing devices configured to perform specific functions.

Computing environment 100 also may include one or more computing platforms. For example, computing environment 100 may include client authentication computing platform 110. As illustrated in greater detail below, client authentication computing platform 110 may include one or more computing devices configured to perform one or more of the functions described herein. For example, client authentication computing platform 110 may include one or more computers (e.g., laptop computers, desktop computers, servers, server blades, or the like).

Computing environment 100 also may include one or more networks, which may interconnect one or more of client authentication computing platform 110, client portal server 120, client support server 130, administrative computing device 140, social messaging server 150, client computing device 160, client computing device 170, and client computing device 180. For example, computing environment 100 may include public network 190 and private network 195. Private network 195 and/or public network 190 may include one or more sub-networks (e.g., local area networks (LANs), wide area networks (WANs), or the like). Private network 195 may be associated with a particular organization (e.g., a corporation, financial institution, educational institution, governmental institution, or the like) and may interconnect one or more computing devices associated with the organization. For example, client authentication computing platform 110, client portal server 120, client support server 130, and administrative computing device 140 may be associated with an organization (e.g., a financial institution), and private network 195 may be associated with and/or operated by the organization, and may include one or more networks (e.g., LANs, WANs, virtual private networks (VPNs), or the like) that interconnect client authentication computing platform 110, client portal server 120, client support server 130, and administrative computing device 140 and one or more other computing devices and/or computer systems that are used by, operated by, and/or otherwise associated with the organization. Public network 190 may connect private network 195 and/or one or more computing devices connected thereto (e.g., client authentication computing platform 110, client portal server 120, client support server 130, and administrative computing device 140) with one or more networks and/or computing devices that are not associated with the organization. For example, social messaging server 150, client computing device 160, client computing device 170, and client computing device 180 might not be associated with an organization that operates private network 195 (e.g., because social messaging server 150, client computing device 160, client computing device 170, and client computing device 180 may be owned, operated, and/or serviced by one or more entities different from the organization that operates private network 195, such as one or more customers of the organization and/or vendors of the organization, rather than being owned and/or operated by the organization itself or an employee or affiliate of the organization), and public network 190 may include one or more networks (e.g., the internet) that connect social messaging server 150, client computing device 160, client computing device 170, and client computing device 180 to private network 195 and/or one or more computing devices connected thereto (e.g., client authentication computing platform 110, client portal server 120, client support server 130, and administrative computing device 140).

Referring to FIG. 1B, client authentication computing platform 110 may include one or more processors 111, memory 112, and communication interface 115. A data bus may interconnect processor(s) 111, memory 112, and communication interface 115. Communication interface 115 may be a network interface configured to support communication between client authentication computing platform 110 and one or more networks (e.g., private network 195, public network 190, or the like). Memory 112 may include one or more program modules having instructions that when executed by processor(s) 111 cause client authentication computing platform 110 to perform one or more functions described herein and/or one or more databases that may store and/or otherwise maintain information which may be used by such program modules and/or processor(s) 111. In some instances, the one or more program modules and/or databases may be stored by and/or maintained in different memory units of client authentication computing platform 110 and/or by different computing devices that may form and/or otherwise make up client authentication computing platform 110. For example, memory 112 may have, store, and/or include a client authentication module 113 and a client authentication database 114. Client authentication module 113 may have instructions that direct and/or cause client authentication computing platform 110 to authenticate one or more users and/or devices using tokenized authentication techniques and/or to perform other functions, as discussed in greater detail below. Client authentication database 114 may store information used by client authentication module 113 and/or client authentication computing platform 110 in authenticating one or more users and/or devices using tokenized authentication techniques and/or in performing other functions.

FIGS. 2A-2N depict an illustrative event sequence for preventing unauthorized access to secured information systems using tokenized authentication techniques in accordance with one or more example embodiments. Referring to FIG. 2A, at step 201, client computing device 160 may register with client authentication computing platform 110. For example, in registering with client authentication computing platform 110 at step 201, client computing device 160 may send, to client authentication computing platform 110, registration information identifying a specific user account associated with a social messaging service provided by social messaging server 150. The user account may, for example, be linked to and/or used by a user of client computing device 160 for communicating via the social messaging service provided by social messaging server 150. At step 202, client authentication computing platform 110 may store registration information. For example, in storing registration information at step 202, client authentication computing platform 110 may store user account information associated with one or more users of client computing device 160, device information associated with client computing device 160, and/or the like, including some or all of the information received from client computing device 160 (e.g., during registration at step 201).

At step 203, client authentication computing platform 110 may register with social messaging server 150. For example, at step 203, client authentication computing platform 110 may register with social messaging server 150 based on client computing device 160 registering with client authentication computing platform 110, as this may enable client authentication computing platform 110 to obtain and/or exchange user account information, device information, and/or other information associated with client computing device 160 and/or a social messaging service account used by a user of client computing device 160 with social messaging server 150. For instance, in registering with social messaging server 150 at step 203, client authentication computing platform 110 may receive one or more tokens and/or other information from social messaging server 150, and the one or more tokens and/or other information received from social messaging server 150 may be associated with one or more user accounts linked to client computing device 160 (which may, e.g., include a client portal user account associated with client portal server 120 and linked to client computing device 160, as well as a social messaging service user account associated with social messaging server 150 and linked to client computing device 160).

At step 204, client authentication computing platform 110 may store token information. For example, at step 204, client authentication computing platform 110 may store token information that enables client authentication computing platform 110 to authenticate social messaging server 150 and/or enables social messaging server 150 to authenticate client authentication computing platform 110, so that client authentication computing platform 110 and social messaging server 150 are able to exchange information associated with client computing device 160 and/or one or more user accounts linked to client computing device 160 (e.g., a client portal user account associated with client portal server 120 and linked to client computing device 160, a social messaging service user account associated with social messaging server 150 and linked to client computing device 160). For instance, both client authentication computing platform 110 and social messaging server 150 may maintain tokens enabling them to authenticate each other and individual users to secured sessions. In some instances, client authentication computing platform 110 and social messaging server 150 may utilize OAUTH standards, and one or more tokens generated and/or maintained by client authentication computing platform 110 and/or social messaging server 150 may be defined in accordance with OAUTH standards.

Referring to FIG. 2B, at step 205, client portal server 120 may generate a notification. For example, in generating a notification at step 205, client portal server 120 may generate a client alert for client computing device 160 and/or a client portal user account linked to client computing device 160. The client alert generated by client portal server 120 for client computing device 160 and/or the client portal user account linked to client computing device 160 may, for instance, include information indicating that one or more new account statements and/or other documents are available, one or more special offers are available, unusual account activity has been detected, and/or the like. In some instances, the notification generated by client portal server 120 at step 205 may include a selectable link that has been tokenized, for example, to include a unique identifier linked to a specific user account associated with a client portal provided by client portal server 120 and/or a specific page or other interface of a client portal provided by client portal server 120 (which may, e.g., be a specific user interface of an online banking portal or a mobile banking portal provided by client portal server 120). As illustrated in greater detail below, by generating a notification that includes a tokenized link, client portal server 120 may enable context and/or contextual information to be passed from a social messaging application presenting the notification generated by client portal server 120 to a client portal application (which may, e.g., be a mobile banking application configured to present a mobile banking portal or a web browser configured to present an online banking portal) that may open and/or present the linked content that is embedded in and/or otherwise associated with the notification generated by client portal server 120.

At step 206, client portal server 120 may send the notification to social messaging server 150 (e.g., based on one or more user preferences associated with the client portal user account linked to client computing device 160 indicating that one or more notifications should be sent to client computing device 160 via a social messaging service provided by social messaging server 150). At step 207, social messaging server 150 may send a message to client computing device 160. For example, at step 207, social messaging server 150 may send a message to client computing device 160 via a social messaging service provided by social messaging server 150, and the message may include the notification generated by and received from client portal server 120.

At step 208, client computing device 160 may present the message received from social messaging server 150. For example, in presenting the message received from social messaging server 150 at step 208, client computing device 160 may display and/or otherwise present a graphical user interface similar to graphical user interface 300, which is illustrated in FIG. 3. As seen in FIG. 3, graphical user interface 300 may be a chat interface associated with a social messaging service provided by social messaging server 150. For example, graphical user interface 300 may include information identifying the source of the message (e.g., “New Message from Company 1”), as well as the content of the notification received from client portal server 120 including the tokenized link (e.g., “Hello, <First1 Last1>! We wanted to let you know that your most recent statement is now available. Please click here to access your documents.” and “You can select the above link, which is unique to you, to access your documents via a client portal. Please note that you may be prompted to provide one or more authentication credentials.”). In addition, graphical user interface 300 may include one or more controls and/or other elements enabling a user of graphical user interface 300 and/or client computing device 160 to respond to the message (e.g., a message text entry field, a send button, and/or the like).

Referring to FIG. 2C, at step 209, client computing device 160 may receive input selecting a tokenized link (e.g., the tokenized link included in the message presented by client computing device 160 at step 208). At step 210, client computing device 160 may send a request for the content associated with the tokenized link to client portal server 120 (e.g., in response to receiving the input selecting the tokenized link at step 209). For example, at step 210, client computing device 160 may open the tokenized link included in the message presented by client computing device 160 at step 208, and the tokenized link may initially direct a browser application or object executing on client computing device 160 to client portal server 120.

At step 211, client portal server 120 may receive the request for the content associated with the tokenized link from client computing device 160. At step 212, client portal server 120 may send an authentication request to client authentication computing platform 110 (e.g., in response to receiving the request for the content associated with the tokenized link from client computing device 160 at step 211). For example, at step 212, client portal server 120 may send an authentication request to client authentication computing platform 110 that includes information from the tokenized link, which may include information identifying a user account associated with a client portal provided by client portal server 120 to which access is being requested by client computing device 160, a user account associated with the social messaging service provided by social messaging server 150 which is being used by client computing device 160 to send and/or receive messages, and/or other information, such as device information identifying client computing device 160, as illustrated in greater detail below. Client computing device 160 and/or the user of client computing device 160 may, for instance, already be authenticated to the social messaging service user account linked to client computing device 160 and used by the user of client computing device 160 to communicate via the social messaging service provided by social messaging server 150.

Referring to FIG. 2D, at step 213, client authentication computing platform 110 may receive the authentication request from client portal server 120. For example, at step 213, client authentication computing platform 110 may receive, via the communication interface (e.g., communication interface 115), and from a client portal server (e.g., client portal server 120), a request to authenticate a first user to a first user account associated with a client portal provided by the client portal server (e.g., client portal server 120).

In some embodiments, the request to authenticate the first user to the first user account associated with the client portal provided by the client portal server may include information indicating that a first tokenized link included in a notification generated by the client portal server and sent via a social messaging service provided by the social messaging server has been selected. For example, the request to authenticate the first user to the first user account associated with the client portal provided by the client portal server (which may, e.g., be received by client authentication computing platform 110 from client portal server 120 at step 213) may include information indicating that a first tokenized link included in a notification generated by the client portal server (e.g., client portal server 120) and sent via a social messaging service provided by the social messaging server (e.g., social messaging server 150) has been selected. In some instances, the request to authenticate the first user to the first user account associated with the client portal provided by the client portal server (e.g., client portal server 120) may include information identifying a social messaging service user account associated with the request as well as a client portal user account associated with the request.

In some embodiments, the first tokenized link may include a unique identifier linked to the first user account associated with the client portal provided by the client portal server and a first interface of the client portal provided by the client portal server. For example, the first tokenized link (which may, e.g., have been selected by the user of client computing device 160) may include a unique identifier linked to the first user account associated with the client portal provided by the client portal server (e.g., client portal server 120) and a first interface of the client portal provided by the client portal server (e.g., client portal server 120). For instance, the tokenized link may include a unique identifier linked to a specific user account and linked to a specific page or other interface of a client portal. As illustrated in greater detail below, this may, for example, enable context to be passed from a social messaging application executing on client computing device 160 to an online banking application executing on client computing device 160 and/or mobile banking application executing on client computing device 160, as once the user of client computing device 160 is authenticated to the corresponding online banking account and/or mobile banking account, the online banking application executing on client computing device 160 and/or mobile banking application executing on client computing device 160 may be opened directly to the page and/or interface corresponding to the tokenized link.

At step 214, client authentication computing platform 110 may send an authentication token request message to social messaging server 150. For example, based on receiving the request to authenticate the first user to the first user account associated with the client portal provided by the client portal server (e.g., client portal server 120), client authentication computing platform 110 may send, via the communication interface (e.g., communication interface 115), and to a social messaging server (e.g., social messaging server 150), a first authentication token request message. The authentication token request message may, for instance, request a session token from social messaging server 150. In some instances, the session token requested from social messaging server 150 by client authentication computing platform 110 may be an access token that is created and/or formulated (e.g., by social messaging server 150) based on one or more authentication standards, such as OAUTH standards.

In some embodiments, the first authentication token request message may include information identifying a first social messaging service account associated with the social messaging service provided by the social messaging server. For example, the first authentication token request message (which may, e.g., be sent by client authentication computing platform 110 to social messaging server 150 at step 214) may include information identifying a first social messaging service account associated with the social messaging service provided by the social messaging server (e.g., social messaging server 150). For instance, the authentication token request message may include information identifying a specific social messaging user account associated with the social messaging service provided by social messaging server 150 (e.g., corresponding to the social messaging user account that received the message and selected the tokenized link) and linked to a specific client portal user account, such as a specific online banking account and/or mobile banking account associated with a specific customer of a financial institution.

At step 215, social messaging server 150 may receive the authentication token request message from client authentication computing platform 110. At step 216, social messaging server 150 may send an authentication token to client authentication computing platform 110 (e.g., in response to the authentication token request message received from client authentication computing platform 110 at step 215). For example, at step 216, social messaging server 150 may send an authentication token to client authentication computing platform 110 that enables client authentication computing platform 110 to authenticate a user of the social messaging service provided by social messaging server 150 in connection with a specific social messaging service session so as to provide the user with access to one or more resources (e.g., maintained by client authentication computing platform 110, client portal server 120, and/or client support server 130) in a specific client portal session and/or client support session. In this way, and as illustrated in greater detail below, the user's authentication status with respect to a social messaging user account on the social messaging service provided by social messaging server 150 may be carried over to a client portal session (which may, e.g., be provided by client portal server 120) and/or a client support session (which may, e.g., be provided by client support server 130) involving the user's client portal user account (which may, e.g., be used by the user to access to a client portal provided by client portal server 120).

Referring to FIG. 2E, at step 217, client authentication computing platform 110 may receive the authentication token from social messaging server 150. For example, at step 217, client authentication computing platform 110 may receive, via the communication interface (e.g., communication interface 115), and from the social messaging server (e.g., social messaging server 150), a first authentication token. The authentication token (which may, e.g., be received by client authentication computing platform 110 at step 217) may, for instance, be a session token and/or may include information identifying a social messaging service user account associated with the authentication request (e.g., identifying a social messaging service user account associated with client computing device 160), information identifying a client portal user account associated with the authentication request (e.g., identifying a client portal user account associated with client computing device 160), information identifying a device associated with the authentication request (e.g., identifying client computing device 160, such as a device name, device identifier, network address, and/or the like), one or more keys, certificates, and/or unique identifiers, and/or other information.

In some embodiments, the first authentication token received from the social messaging server may include information indicating that the first user is authenticated to the first social messaging service account associated with the social messaging service provided by the social messaging server. For example, the first authentication token received from the social messaging server (e.g., social messaging server 150) may include information indicating that the first user is authenticated to the first social messaging service account associated with the social messaging service provided by the social messaging server (e.g., social messaging server 150).

At step 218, client authentication computing platform 110 may validate the authentication token received from social messaging server 150. For example, at step 218, client authentication computing platform 110 may validate the first authentication token received from the social messaging server (e.g., social messaging server 150). In validating the first authentication token received from the social messaging server (e.g., social messaging server 150), client authentication computing platform 110 may, for instance, determine whether and/or confirm that the first authentication token received from the social messaging server (e.g., social messaging server 150) is valid based on the contents of the first authentication token received from the social messaging server (e.g., social messaging server 150). If client authentication computing platform 110 determines that the first authentication token received from the social messaging server (e.g., social messaging server 150) is not valid, client authentication computing platform 110 may generate and/or send one or more error messages, and the event sequence may end. Otherwise, if client authentication computing platform 110 determines that the first authentication token received from the social messaging server (e.g., social messaging server 150) is valid, the example event sequence may continue as illustrated.

At step 219, client authentication computing platform 110 may generate an authentication prompt. For example, at step 219, client authentication computing platform 110 may generate a first step-up authentication prompt for a first registered client computing device linked to the first user account (e.g., client computing device 160). The step-up authentication prompt may, for example, be a biometric authentication prompt (e.g., prompting a recipient device and/or user to provide biometric input for validation, such as fingerprint biometric input, voiceprint biometric input, facial or retinal biometric input, and/or other biometric input), a one-time passcode authentication prompt, a username and password authentication prompt, a security question authentication prompt, and/or the like. In some instances, client authentication computing platform 110 may generate and/or send such a step-up authentication prompt in instances in which client computing device 160 and/or the user of client computing device 160 cannot be authenticated based solely on validating the authentication token received from social messaging server 150 (e.g., because of individual user settings, because of information security policies, because of current information security state information, and/or the like).

At step 220, client authentication computing platform 110 may send the authentication prompt to client computing device 160. For example, at step 220, client authentication computing platform 110 may send, via the communication interface (e.g., communication interface 115), and to the first registered client computing device linked to the first user account (e.g., client computing device 160), the first step-up authentication prompt generated for the first registered client computing device linked to the first user account (e.g., client computing device 160).

Referring to FIG. 2F, at step 221, client computing device 160 may present the authentication prompt received by client computing device 160 from client authentication computing platform 110. For example, in presenting the authentication prompt received by client computing device 160 from client authentication computing platform 110, client computing device 160 may display and/or otherwise present a graphical user interface similar to graphical user interface 400, which is illustrated in FIG. 4. As seen in FIG. 4, graphical user interface 400 may be presented by an operating system executing on client computing device 160 and/or by a mobile banking application executing on client computing device 160, and graphical user interface 400 may include information prompting the user to respond to the biometric prompt generated by client authentication computing platform 110 (e.g., “We have received your request to access your documents. To proceed, please provide biometric input for validation”).

At step 222, client computing device 160 may send an authentication prompt response to client authentication computing platform 110. For example, in sending the authentication prompt response to client authentication computing platform 110 at step 222, client computing device 160 may send information indicating that a valid response to the authentication prompt was received by client computing device 160 (e.g., information indicating that valid biometric input was received by client computing device 160 from the user of client computing device 160) and/or information for validation by client authentication computing platform 110 (e.g., returning a one-time passcode, username, password, and/or security question response received by client computing device 160 from the user of client computing device 160 to be validated by client authentication computing platform 110).

At step 223, client authentication computing platform 110 may validate the authentication prompt response received from client computing device 160. For example, at step 223, client authentication computing platform 110 may validate a first response to the first step-up authentication prompt generated for the first registered client computing device linked to the first user account (e.g., client computing device 160). In validating the authentication prompt response received from client computing device 160, client authentication computing platform 110 may, for instance, determine whether and/or confirm that the authentication prompt response received from client computing device 160 is valid based on the contents of the authentication prompt response received from client computing device 160 and based on the authentication prompt that client authentication computing platform 110 generated and sent to client computing device 160. If client authentication computing platform 110 determines that the authentication prompt response received from client computing device 160 is not valid, client authentication computing platform 110 may generate and/or send one or more error messages, and the event sequence may end. Otherwise, if client authentication computing platform 110 determines that the authentication prompt response received from client computing device 160 is valid, the example event sequence may continue as illustrated.

At step 224, client authentication computing platform 110 may generate a validation message (e.g., based on validating the authentication token received from social messaging server 150 and/or based on validating the authentication prompt response received from client computing device 160). For example, at step 224, based on validating the first authentication token received from the social messaging server (e.g., social messaging server 150), client authentication computing platform 110 may generate a first validation message directing the client portal server (e.g., client portal server 120) to provide the first user with access to the first user account. As illustrated in greater detail below, the validation message directing the client portal server (e.g., client portal server 120) to provide the user with access to the user account may cause client portal server 120 to generate and/or present one or more pages and/or other interfaces of a client portal, such as an online banking portal and/or a mobile banking portal, that correspond to and/or are otherwise associated with the tokenized link sent to the user of client computing device 160 by client portal server 120 via the social messaging service provided by social messaging server 150.

In some embodiments, the first validation message directing the client portal server to provide the first user with access to the first user account may include information indicating that the first user has been authenticated to the first user account based on the first authentication token received from the social messaging server. For example, the first validation message directing the client portal server (e.g., client portal server 120) to provide the first user with access to the first user account may include information indicating that the first user has been authenticated to the first user account based on the first authentication token received from the social messaging server (e.g., social messaging server 150). Such information may, for instance, be used by client portal server 120 in subsequently determining that one or more step-up authentication prompts might be needed to use specific functions of the client portal, such as funds transfer functions and/or other functions requiring relatively higher levels of authentication and/or information security.

In some instances in which client authentication computing platform 110 generates and sends a step-up authentication prompt to client computing device 160, the first validation message directing the client portal server (e.g., client portal server 120) to provide the first user with access to the first user account may be generated based on validating the first response to the first step-up authentication prompt generated for the first registered client computing device linked to the first user account (e.g., client computing device 160) and based on validating the first authentication token received from the social messaging server (e.g., social messaging server 150).

Referring to FIG. 2G, at step 225, client authentication computing platform 110 may send the validation message to client portal server 120 (e.g., directing client portal server 120 to provide access). For example, at step 225, client authentication computing platform 110 may send, via the communication interface (e.g., communication interface 115), and to the client portal server (e.g., client portal server 120), the first validation message directing the client portal server (e.g., client portal server 120) to provide the first user with access to the first user account. In directing the client portal server (e.g., client portal server 120) to provide the first user with access to the first user account, client authentication computing platform 110 also may direct and/or cause client portal server 120 to generate and/or present one or more pages and/or other interfaces of a client portal, such as an online banking portal and/or a mobile banking portal, that correspond to and/or are otherwise associated with the tokenized link sent to the user of client computing device 160 by client portal server 120 via the social messaging service provided by social messaging server 150, as illustrated in greater detail below.

At step 226, client portal server 120 may receive the validation message from client authentication computing platform 110. At step 227, client portal server 120 may generate a portal interface. For example, at step 227, client portal server 120 may generate a portal interface configured to present linked content and/or a specific interface corresponding to the tokenized link selected by the user of client computing device 160 from the message sent to the user of client computing device 160 by client portal server 120 via the social messaging service provided by social messaging server 150. For instance, if the user of client computing device 160 selected a tokenized link associated with specific account documents, client portal server 120 may generate a portal interface configured to present the specific account documents. As another example, if the user of client computing device 160 selected a tokenized link associated with specific account offers, client portal server 120 may generate a portal interface configured to present the specific account offers. As another example, if the user of client computing device 160 selected a tokenized link associated with a low balance alert, client portal server 120 may generate a portal interface configured to present the alert and/or one or more options to transfer funds.

At step 228, client portal server 120 may provide the portal interface to client computing device 160. For example, in providing the portal interface to client computing device 160, client portal server 120 may send the portal interface to client computing device 160 and direct and/or cause client computing device 160 to present the portal interface, which may cause client computing device 160 to display and/or otherwise present a graphical user interface similar to graphical user interface 500, which is illustrated in FIG. 5. As seen in FIG. 5, graphical user interface 500 may be a client portal interface, such as an online banking portal interface or a mobile banking portal interface, and may be displayed and/or otherwise presented by a browser application executing on client computing device 160 and/or a mobile banking application executed on client computing device 160. In addition, graphical user interface 500 may include content corresponding to the tokenized link selected by the user of client computing device 160 from the message sent to the user of client computing device 160 by client portal server 120 via the social messaging service provided by social messaging server 150. For example, graphical user interface 500 may include one or more documents corresponding to the tokenized link selected by the user of client computing device 160.

Subsequently, one or more steps of the event sequence discussed above may be repeated by client authentication computing platform 110 and/or the other systems discussed above in authenticating another user to another user account associated with the client portal provided by client portal server 120. Although such steps are illustrated separately and following the steps performed with respect to authenticating the first user, various steps may be performed in a different order, such that client authentication computing platform 110 may, for instance, authenticate multiple users simultaneously as client portal server 120 receives requests from different users and/or devices selecting different tokenized links in different notifications and/or messages originating from client portal server 120 and/or sent via the social messaging service provided by social messaging server 150.

Referring to FIG. 2H, at step 229, client computing device 170 may register with client authentication computing platform 110. For example, in registering with client authentication computing platform 110 at step 229, client computing device 170 may send, to client authentication computing platform 110, registration information identifying a specific user account associated with a social messaging service provided by social messaging server 150. The user account may, for example, be linked to and/or used by a user of client computing device 170 for communicating via the social messaging service provided by social messaging server 150. At step 230, client authentication computing platform 110 may store registration information. For example, in storing registration information at step 230, client authentication computing platform 110 may store user account information associated with one or more users of client computing device 170, device information associated with client computing device 170, and/or the like, including some or all of the information received from client computing device 170 (e.g., during registration at step 229).

At step 231, client authentication computing platform 110 may register with social messaging server 150. For example, at step 231, client authentication computing platform 110 may register with social messaging server 150 based on client computing device 170 registering with client authentication computing platform 110, as this may enable client authentication computing platform 110 to obtain and/or exchange user account information, device information, and/or other information associated with client computing device 170 and/or a social messaging service account used by a user of client computing device 170 with social messaging server 150. For instance, in registering with social messaging server 150 at step 231, client authentication computing platform 110 may receive one or more tokens and/or other information from social messaging server 150, and the one or more tokens and/or other information received from social messaging server 150 may be associated with one or more user accounts linked to client computing device 170 (which may, e.g., include a client portal user account associated with client portal server 120 and linked to client computing device 170, as well as a social messaging service user account associated with social messaging server 150 and linked to client computing device 170).

At step 232, client authentication computing platform 110 may store token information. For example, at step 232, client authentication computing platform 110 may store token information that enables client authentication computing platform 110 to authenticate social messaging server 150 and/or enables social messaging server 150 to authenticate client authentication computing platform 110, so that client authentication computing platform 110 and social messaging server 150 are able to exchange information associated with client computing device 170 and/or one or more user accounts linked to client computing device 170 (e.g., a client portal user account associated with client portal server 120 and linked to client computing device 170, a social messaging service user account associated with social messaging server 150 and linked to client computing device 170). For instance, both client authentication computing platform 110 and social messaging server 150 may maintain tokens enabling them to authenticate each other and individual users to secured sessions. In some instances, client authentication computing platform 110 and social messaging server 150 may utilize OAUTH standards, and one or more tokens generated and/or maintained by client authentication computing platform 110 and/or social messaging server 150 may be defined in accordance with OAUTH standards.

Referring to FIG. 2I, at step 233, client portal server 120 may generate a notification. For example, in generating a notification at step 233, client portal server 120 may generate a client alert for client computing device 170 and/or a client portal user account linked to client computing device 170. The client alert generated by client portal server 120 for client computing device 170 and/or the client portal user account linked to client computing device 170 may, for instance, include information indicating that one or more new account statements and/or other documents are available, one or more special offers are available, unusual account activity has been detected, and/or the like. In some instances, the notification generated by client portal server 120 at step 233 may include a selectable link that has been tokenized, for example, to include a unique identifier linked to a specific user account associated with a client portal provided by client portal server 120 and/or a specific page or other interface of a client portal provided by client portal server 120 (which may, e.g., be a specific user interface of an online banking portal or a mobile banking portal provided by client portal server 120). As illustrated in greater detail below, by generating a notification that includes a tokenized link, client portal server 120 may enable context and/or contextual information to be passed from a social messaging application presenting the notification generated by client portal server 120 to a client portal application (which may, e.g., be a mobile banking application configured to present a mobile banking portal or a web browser configured to present an online banking portal) that may open and/or present the linked content that is embedded in and/or otherwise associated with the notification generated by client portal server 120.

At step 234, client portal server 120 may send the notification to social messaging server 150 (e.g., based on one or more user preferences associated with the client portal user account linked to client computing device 170 indicating that one or more notifications should be sent to client computing device 170 via a social messaging service provided by social messaging server 150). At step 235, social messaging server 150 may send a message to client computing device 170. For example, at step 235, social messaging server 150 may send a message to client computing device 170 via a social messaging service provided by social messaging server 150, and the message may include the notification generated by and received from client portal server 120.

At step 236, client computing device 170 may present the message received from social messaging server 150. For example, in presenting the message received from social messaging server 150 at step 236, client computing device 170 may display and/or otherwise present a graphical user interface similar to graphical user interface 600, which is illustrated in FIG. 6. As seen in FIG. 6, graphical user interface 600 may be a chat interface associated with a social messaging service provided by social messaging server 150. For example, graphical user interface 600 may include information identifying the source of the message (e.g., “New Message from Company 1”), as well as the content of the notification received from client portal server 120 including the tokenized link (e.g., “Hello, <First2 Last2>! We wanted to let you know that a new special offer is now available. Please click here to learn more.” and “You can select the above link, which is unique to you, to access your offers via a client portal. Please note that you may be prompted to provide one or more authentication credentials.”). In addition, graphical user interface 600 may include one or more controls and/or other elements enabling a user of graphical user interface 600 and/or client computing device 170 to respond to the message (e.g., a message text entry field, a send button, and/or the like).

Referring to FIG. 2J, at step 237, client computing device 170 may receive input selecting a tokenized link (e.g., the tokenized link included in the message presented by client computing device 170 at step 236). At step 238, client computing device 170 may send a request for the content associated with the tokenized link to client portal server 120 (e.g., in response to receiving the input selecting the tokenized link at step 237). For example, at step 238, client computing device 170 may open the tokenized link included in the message presented by client computing device 170 at step 236, and the tokenized link may initially direct a browser application or object executing on client computing device 170 to client portal server 120.

At step 239, client portal server 120 may receive the request for the content associated with the tokenized link from client computing device 170. At step 240, client portal server 120 may send an authentication request to client authentication computing platform 110 (e.g., in response to receiving the request for the content associated with the tokenized link from client computing device 170 at step 239). For example, at step 240, client portal server 120 may send an authentication request to client authentication computing platform 110 that includes information from the tokenized link, which may include information identifying a user account associated with a client portal provided by client portal server 120 to which access is being requested by client computing device 170, a user account associated with the social messaging service provided by social messaging server 150 which is being used by client computing device 170 to send and/or receive messages, and/or other information, such as device information identifying client computing device 170, as illustrated in greater detail below. Client computing device 170 and/or the user of client computing device 170 may, for instance, already be authenticated to the social messaging service user account linked to client computing device 170 and used by the user of client computing device 170 to communicate via the social messaging service provided by social messaging server 150.

Referring to FIG. 2K, at step 241, client authentication computing platform 110 may receive the authentication request from client portal server 120. For example, at step 241, client authentication computing platform 110 may receive, via the communication interface (e.g., communication interface 115), and from the client portal server (e.g., client portal server 120), a request to authenticate a second user to a second user account associated with the client portal provided by the client portal server (e.g., client portal server 120).

In some embodiments, the request to authenticate the second user to the second user account associated with the client portal provided by the client portal server may include information indicating that a second tokenized link included in a notification generated by the client portal server and sent via a social messaging service provided by the social messaging server has been selected. For example, the request to authenticate the second user to the second user account associated with the client portal provided by the client portal server (which may, e.g., be received by client authentication computing platform 110 from client portal server 120 at step 241) may include information indicating that a second tokenized link included in a notification generated by the client portal server (e.g., client portal server 120) and sent via a social messaging service provided by the social messaging server (e.g., social messaging server 150) has been selected. In some instances, the request to authenticate the second user to the second user account associated with the client portal provided by the client portal server (e.g., client portal server 120) may include information identifying a social messaging service user account associated with the request as well as a client portal user account associated with the request.

In some embodiments, the second tokenized link may include a unique identifier linked to the second user account associated with the client portal provided by the client portal server and a second interface of the client portal provided by the client portal server. For example, the second tokenized link (which may, e.g., have been selected by the user of client computing device 170) may include a unique identifier linked to the second user account associated with the client portal provided by the client portal server (e.g., client portal server 120) and a second interface of the client portal provided by the client portal server (e.g., client portal server 120). For instance, the tokenized link may include a unique identifier linked to a specific user account and linked to a specific page or other interface of a client portal. As illustrated in greater detail below, this may, for example, enable context to be passed from a social messaging application executing on client computing device 170 to an online banking application executing on client computing device 170 and/or mobile banking application executing on client computing device 170, as once the user of client computing device 170 is authenticated to the corresponding online banking account and/or mobile banking account, the online banking application executing on client computing device 170 and/or mobile banking application executing on client computing device 170 may be opened directly to the page and/or interface corresponding to the tokenized link.

At step 242, client authentication computing platform 110 may send an authentication token request message to social messaging server 150. For example, based on receiving the request to authenticate the second user to the second user account associated with the client portal provided by the client portal server (e.g., client portal server 120), client authentication computing platform 110 may send, via the communication interface (e.g., communication interface 115), and to the social messaging server (e.g., social messaging server 150), a second authentication token request message. The authentication token request message may, for instance, request a session token from social messaging server 150. In some instances, the session token requested from social messaging server 150 by client authentication computing platform 110 may be an access token that is created and/or formulated (e.g., by social messaging server 150) based on one or more authentication standards, such as OAUTH standards.

In some embodiments, the second authentication token request message may include information identifying a second social messaging service account associated with the social messaging service provided by the social messaging server. For example, the second authentication token request message (which may, e.g., be sent by client authentication computing platform 110 to social messaging server 150 at step 242) may include information identifying a second social messaging service account associated with the social messaging service provided by the social messaging server (e.g., social messaging server 150). For instance, the authentication token request message may include information identifying a specific social messaging user account associated with the social messaging service provided by social messaging server 150 (e.g., corresponding to the social messaging user account that received the message and selected the tokenized link) and linked to a specific client portal user account, such as a specific online banking account and/or mobile banking account associated with a specific customer of a financial institution.

At step 243, social messaging server 150 may receive the authentication token request message from client authentication computing platform 110. At step 244, social messaging server 150 may send an authentication token to client authentication computing platform 110 (e.g., in response to the authentication token request message received from client authentication computing platform 110 at step 243). For example, at step 244, social messaging server 150 may send an authentication token to client authentication computing platform 110 that enables client authentication computing platform 110 to authenticate a user of the social messaging service provided by social messaging server 150 in connection with a specific social messaging service session so as to provide the user with access to one or more resources (e.g., maintained by client authentication computing platform 110, client portal server 120, and/or client support server 130) in a specific client portal session and/or client support session. In this way, and as illustrated in greater detail below, the user's authentication status with respect to a social messaging user account on the social messaging service provided by social messaging server 150 may be carried over to a client portal session (which may, e.g., be provided by client portal server 120) and/or a client support session (which may, e.g., be provided by client support server 130) involving the user's client portal user account (which may, e.g., be used by the user to access to a client portal provided by client portal server 120).

Referring to FIG. 2L, at step 245, client authentication computing platform 110 may receive the authentication token from social messaging server 150. For example, at step 245, client authentication computing platform 110 may receive, via the communication interface (e.g., communication interface 115), and from the social messaging server (e.g., social messaging server 150), a second authentication token. The authentication token (which may, e.g., be received by client authentication computing platform 110 at step 245) may, for instance, be a session token and/or may include information identifying a social messaging service user account associated with the authentication request (e.g., identifying a social messaging service user account associated with client computing device 170), information identifying a client portal user account associated with the authentication request (e.g., identifying a client portal user account associated with client computing device 170), information identifying a device associated with the authentication request (e.g., identifying client computing device 170, such as a device name, device identifier, network address, and/or the like), one or more keys, certificates, and/or unique identifiers, and/or other information.

In some embodiments, the second authentication token received from the social messaging server may include information indicating that the second user is authenticated to the second social messaging service account associated with the social messaging service provided by the social messaging server. For example, the second authentication token received from the social messaging server (e.g., social messaging server 150) may include information indicating that the second user is authenticated to the second social messaging service account associated with the social messaging service provided by the social messaging server (e.g., social messaging server 150).

At step 246, client authentication computing platform 110 may validate the authentication token received from social messaging server 150. For example, at step 246, client authentication computing platform 110 may validate the second authentication token received from the social messaging server (e.g., social messaging server 150). In validating the second authentication token received from the social messaging server (e.g., social messaging server 150), client authentication computing platform 110 may, for instance, determine whether and/or confirm that the second authentication token received from the social messaging server (e.g., social messaging server 150) is valid based on the contents of the second authentication token received from the social messaging server (e.g., social messaging server 150). If client authentication computing platform 110 determines that the second authentication token received from the social messaging server (e.g., social messaging server 150) is not valid, client authentication computing platform 110 may generate and/or send one or more error messages, and the event sequence may end. Otherwise, if client authentication computing platform 110 determines that the second authentication token received from the social messaging server (e.g., social messaging server 150) is valid, the example event sequence may continue as illustrated.

At step 247, client authentication computing platform 110 may generate an authentication prompt. For example, at step 247, client authentication computing platform 110 may generate a second step-up authentication prompt for a second registered client computing device linked to the second user account (e.g., client computing device 170). The step-up authentication prompt may, for example, be a biometric authentication prompt (e.g., prompting a recipient device and/or user to provide biometric input for validation, such as fingerprint biometric input, voiceprint biometric input, facial or retinal biometric input, and/or other biometric input), a one-time passcode authentication prompt, a username and password authentication prompt, a security question authentication prompt, and/or the like. In some instances, client authentication computing platform 110 may generate and/or send such a step-up authentication prompt in instances in which client computing device 170 and/or the user of client computing device 170 cannot be authenticated based solely on validating the authentication token received from social messaging server 150 (e.g., because of individual user settings, because of information security policies, because of current information security state information, and/or the like).

At step 248, client authentication computing platform 110 may send the authentication prompt to client computing device 170. For example, at step 248, client authentication computing platform 110 may send, via the communication interface (e.g., communication interface 115), and to the second registered client computing device linked to the second user account (e.g., client computing device 170), the second step-up authentication prompt generated for the second registered client computing device linked to the second user account (e.g., client computing device 170).

Referring to FIG. 2M, at step 249, client computing device 170 may present the authentication prompt received by client computing device 170 from client authentication computing platform 110. For example, in presenting the authentication prompt received by client computing device 170 from client authentication computing platform 110, client computing device 170 may display and/or otherwise present a graphical user interface similar to graphical user interface 700, which is illustrated in FIG. 7. As seen in FIG. 7, graphical user interface 700 may be presented by an operating system executing on client computing device 170 and/or by a mobile banking application executing on client computing device 170, and graphical user interface 700 may include information prompting the user to respond to the biometric prompt generated by client authentication computing platform 110 (e.g., “We have received your request to access your offers. To proceed, please provide biometric input for validation”).

At step 250, client computing device 170 may send an authentication prompt response to client authentication computing platform 110. For example, in sending the authentication prompt response to client authentication computing platform 110 at step 250, client computing device 170 may send information indicating that a valid response to the authentication prompt was received by client computing device 170 (e.g., information indicating that valid biometric input was received by client computing device 170 from the user of client computing device 170) and/or information for validation by client authentication computing platform 110 (e.g., returning a one-time passcode, username, password, and/or security question response received by client computing device 170 from the user of client computing device 170 to be validated by client authentication computing platform 110).

At step 251, client authentication computing platform 110 may validate the authentication prompt response received from client computing device 170. For example, at step 251, client authentication computing platform 110 may validate a second response to the second step-up authentication prompt generated for the second registered client computing device linked to the second user account (e.g., client computing device 170). In validating the authentication prompt response received from client computing device 170, client authentication computing platform 110 may, for instance, determine whether and/or confirm that the authentication prompt response received from client computing device 170 is valid based on the contents of the authentication prompt response received from client computing device 170 and based on the authentication prompt that client authentication computing platform 110 generated and sent to client computing device 170. If client authentication computing platform 110 determines that the authentication prompt response received from client computing device 170 is not valid, client authentication computing platform 110 may generate and/or send one or more error messages, and the event sequence may end. Otherwise, if client authentication computing platform 110 determines that the authentication prompt response received from client computing device 170 is valid, the example event sequence may continue as illustrated.

At step 252, client authentication computing platform 110 may generate a validation message (e.g., based on validating the authentication token received from social messaging server 150 and/or based on validating the authentication prompt response received from client computing device 170). For example, at step 252, based on validating the second authentication token received from the social messaging server (e.g., social messaging server 150), client authentication computing platform 110 may generate a second validation message directing the client portal server (e.g., client portal server 120) to provide the second user with access to the second user account. As illustrated in greater detail below, the validation message directing the client portal server (e.g., client portal server 120) to provide the user with access to the user account may cause client portal server 120 to generate and/or present one or more pages and/or other interfaces of a client portal, such as an online banking portal and/or a mobile banking portal, that correspond to and/or are otherwise associated with the tokenized link sent to the user of client computing device 170 by client portal server 120 via the social messaging service provided by social messaging server 150.

In some embodiments, the second validation message directing the client portal server to provide the second user with access to the second user account may include information indicating that the second user has been authenticated to the second user account based on the second authentication token received from the social messaging server. For example, the second validation message directing the client portal server (e.g., client portal server 120) to provide the second user with access to the second user account may include information indicating that the second user has been authenticated to the second user account based on the second authentication token received from the social messaging server (e.g., social messaging server 150). Such information may, for instance, be used by client portal server 120 in subsequently determining that one or more step-up authentication prompts might be needed to use specific functions of the client portal, such as funds transfer functions and/or other functions requiring relatively higher levels of authentication and/or information security.

In some instances in which client authentication computing platform 110 generates and sends a step-up authentication prompt to client computing device 170, the second validation message directing the client portal server (e.g., client portal server 120) to provide the second user with access to the second user account may be generated based on validating the second response to the second step-up authentication prompt generated for the second registered client computing device linked to the second user account (e.g., client computing device 170) and based on validating the second authentication token received from the social messaging server (e.g., social messaging server 150).

Referring to FIG. 2N, at step 253, client authentication computing platform 110 may send the validation message to client portal server 120 (e.g., directing client portal server 120 to provide access). For example, at step 253, client authentication computing platform 110 may send, via the communication interface (e.g., communication interface 115), and to the client portal server (e.g., client portal server 120), the second validation message directing the client portal server (e.g., client portal server 120) to provide the second user with access to the second user account. In directing the client portal server (e.g., client portal server 120) to provide the second user with access to the second user account, client authentication computing platform 110 also may direct and/or cause client portal server 120 to generate and/or present one or more pages and/or other interfaces of a client portal, such as an online banking portal and/or a mobile banking portal, that correspond to and/or are otherwise associated with the tokenized link sent to the user of client computing device 170 by client portal server 120 via the social messaging service provided by social messaging server 150, as illustrated in greater detail below.

At step 254, client portal server 120 may receive the validation message from client authentication computing platform 110. At step 255, client portal server 120 may generate a portal interface. For example, at step 255, client portal server 120 may generate a portal interface configured to present linked content and/or a specific interface corresponding to the tokenized link selected by the user of client computing device 170 from the message sent to the user of client computing device 170 by client portal server 120 via the social messaging service provided by social messaging server 150. For instance, if the user of client computing device 170 selected a tokenized link associated with specific account documents, client portal server 120 may generate a portal interface configured to present the specific account documents. As another example, if the user of client computing device 170 selected a tokenized link associated with specific account offers, client portal server 120 may generate a portal interface configured to present the specific account offers. As another example, if the user of client computing device 170 selected a tokenized link associated with a low balance alert, client portal server 120 may generate a portal interface configured to present the alert and/or one or more options to transfer funds.

At step 256, client portal server 120 may provide the portal interface to client computing device 170. For example, in providing the portal interface to client computing device 170, client portal server 120 may send the portal interface to client computing device 170 and direct and/or cause client computing device 170 to present the portal interface, which may cause client computing device 170 to display and/or otherwise present a graphical user interface similar to graphical user interface 800, which is illustrated in FIG. 8. As seen in FIG. 8, graphical user interface 800 may be a client portal interface, such as an online banking portal interface or a mobile banking portal interface, and may be displayed and/or otherwise presented by a browser application executing on client computing device 170 and/or a mobile banking application executed on client computing device 170. In addition, graphical user interface 800 may include content corresponding to the tokenized link selected by the user of client computing device 170 from the message sent to the user of client computing device 170 by client portal server 120 via the social messaging service provided by social messaging server 150. For example, graphical user interface 800 may include one or more offers corresponding to the tokenized link selected by the user of client computing device 170.

FIG. 9 depicts an illustrative method for preventing unauthorized access to secured information systems using tokenized authentication techniques in accordance with one or more example embodiments. Referring to FIG. 9, at step 905, a computing platform having at least one processor, a memory, and a communication interface may receive, via the communication interface, and from a client portal server, a request to authenticate a first user to a first user account associated with a client portal provided by the client portal server. At step 910, based on receiving the request to authenticate the first user to the first user account associated with the client portal provided by the client portal server, the computing platform may send, via the communication interface, and to a social messaging server, a first authentication token request message. At step 915, the computing platform may receive, via the communication interface, and from the social messaging server, a first authentication token. At step 920, the computing platform may validate the first authentication token received from the social messaging server. At step 925, based on validating the first authentication token received from the social messaging server, the computing platform may generate a first validation message directing the client portal server to provide the first user with access to the first user account. At step 930, the computing platform may send, via the communication interface, and to the client portal server, the first validation message directing the client portal server to provide the first user with access to the first user account.
